Don’t quote me on this, but I believe it should also be compatible with pkmnclassic.net which includes online WFC features such as:

### What works

    GTS
    Battle Videos
    Dressup (PtHGSS)
    Box uploads (PtHGSS)
    Musical photos (BW1/2)
    Wi-Fi Battle Tower and Subway
    Random Match ups (Currently requires AR Code: https://github.com/mm201/pkmn-classic-framework/issues/116)

### What doesn't

    Trainer Rankings (PtHGSS)
    ~~Wi-Fi Plaza (PtHGSS)~~ Seems to work now
